DB-9 Connector Pin-Outs
Communicating with the Console from a remote computer is done through a RS-232 serial port (DB-9 connector) on the
bottom of the console.
Pin layout to connect the Console’s Serial Interface DB-9 connector to a 25-pin computer terminal connector are shown
in Figure 17. These connections are standard for “AT” style modem cables.
